If a mold spore on a piece of drywall is coated with paint. can it come through again and be dangerous to me?

Clean it off, preferably with a fungicide mixture of some kind, and then apply a sealing/barrier paint over it - this will both help stop it coming through, and help match the paint colour when you repaint.





The most important thing is to remove whatever caused the mould in the first place - check humidity, blocked ventilation, leaky roof etc.If a mold spore on a piece of drywall is coated with paint. can it come through again and be dangerous to me?
The paint would not help with what caused the mold in the first place. You need to eliminate the source whether it is a leak roof, water line or pipe in the wall, etc... If you just cover it with paint it will continue to grow inside the wall and you could have a lot bigger problem than you realize. I would suggest finding what caused the mold and completely replacing the affected drywall after you have gotten rid of whatever is causing the mold.If a mold spore on a piece of drywall is coated with paint. can it come through again and be dangerous to me?
yes it can it can kill you from the bactira and just yes it can
clean the wall in bleach then get an antie fungicidal paint
There is a paint product called ';KILZ'; in the US. I don't know for a fact that it actually will kill the mold and spores, but when we paint over a room for a new occupant we use the ';KILZ';. (Comes in white, but can be mixed with a tint. Takes longer to dry.) The signs of mold, spors, water damage, etc., can no longer be seen. I'm guessing if you can't see it, it's a gonner! And then to top it off, we paint the room color on, which takes two coats with a roller. That's three to four coats of paint on top of some little germ! I don't think they live through that. Have not had a person move into a room yet and die from mold spores.
Yes. Mold can come though paint. My father tried to just paint over our mold in our bathroom several times without success. I would try a bleach wash on the wall, and talk to someone at Lowe's or Home Depot about mold removal.
No the paint sealed it and likely killed it so it can no longer germinate. Mold needs basically 3 things to exist and possibly cause disease or allergies. First is moisture, second is a food source like the paper on drywall and proper temp. There are some new drywall materials on the market that do not use cellulose so molds cannot use it as a nutrient source and cannot grow.
yes. the first thing you should do is pray the wall with some bleach water, let it sit until the mold is gone, ( keep wall moist with bleach water ), then wipe dry. then prime the wall with a primer like kiltz that is designed to seal the wall and not let any stain or mildew bleed back out onto the wall after you paint it.
yes, mold will eventually seap through the paint. I had a mold problem and found that making a solution of bleach and water and spraying it on the area several times, dissolved the mold, then after it is removed and completely dry paint over it with special mildew resistant paint.
